ATTACHMENT FOR SHOTGUNSV To all whom it may concern:

Be it known that I, ONESIME E. MICHAUD,

a citizen of the United States, and a resi dentofthe city of St. Louis and State of Missouri, have invented a new and useful Improvement in Attachments for Shotguns, of which the following is a specification.

My invention; relates to shotguns and more particularly to single-barreled guns.

It has for its principal objects to provide for the attachment of a removable extension or choke muzzle section, to secure stability of attachment,and to prevent accidental displacement.

The invention consists in the parts and 'in the arrangements and combinations of barrel showing the notch for cooperating ordinary type.

with the locking lever; Fig. 4 is a side elevation of the parts shown in Figs. 1 and 2; Fig. 5 is a longitudinalvertical section; Fig. 6 is a fragmentary top view of the coupling portions of the gun barrel and muzzle section detached; and Fig. 7 is a vertical section showing a modification of the locking lever and retaining ring.

The gun is a single-barreled gun of any On the forward end of the barrel 1 at the top thereof is a stud or sight 2. In the bottom of the gun barrel is a'rounded notch or'depression 3.

The removable muzzle section or extension 4 is bored to. constitute a continuation of the bore of the gun barrel proper. It may be choke-bored or otherwise bored to suit any particular purpose. The muzzle section has an enlargement or bellportion 5 at its rear end which is counterbored so as to fit over the forward end of the gun barrel 1 and also to provide an annular shoulder (3 adapted to fit squarely against the end of A notch or slot 7 is pro- Specificationof Letters Patent.

Serial No. 483,486.

Mounted on a horizontal pintle in lugs 8 on the bottom of the muzzle section is a locking lever 9. This lever has a circular enlargement 10 at its pivot end which is arranged to project through a slot 11 in the bottom of said muzzle section. This circular enlargement 10 projects into the notch 3 in thebot-tom of the gun barrel 1, and it is adapted to fit snugly therein when the muzzle section is placed on the gun barrel. A portion of the circular enlargement of the locking lever is cut away, as at 12, to clear the outer face of the gun barrel 1 when the lever is moved to turn the circular portion from the notch 3 in attaching and detaching the muzzle section. The forward end of the lever is adapted to fit under an annular offset portion or flange 13 on a ring 14 whichis loosely mounted on the muzzle section next to the bell portion. A portion of the annular flange 13 is cut away or slotted as at 15 to permit the end of the locking lever to pass therethrough; and the outer face of said portion 13 is preferably knurled to facilitate turning the ring. A fixed retaining ring 16 or other suitable device may be provided to prevent the ring from moving endwise on the muzzle section. provided with a curved lateral extension 17 near its forward end, and on the end of this extension is an outwardly offset forwardly projecting lip or extension 18 which terminates on a line with the end of the main rel, the ring 14 is turned to register with thegroove 19 and the locking lever 9 is then swung over and pressed into the groove against the tension of the spring of its curved lateral extension 17 whose end extension 18 rests on the outer face of the annular flange 13 of said ring 14. After the lever is depressed through the slot 15 the ring is turned to move its annular portion over the end of said lever. A continued rotation of the ring will bring its slotted portion 15 under the projecting lip 18 on the spring arm or extension 17 of the lever whereupon said lip 18 will snap into said The I looking lever is slotted portion and lock the ring against rotation. When it is desired to detach the muzzle section the end 18 of the spring arm 17 is lifted from the notch in the ring 14 and said ring is turned until its notch is in line with the main portion of the lever. The lever may then be raised and moved far enough to release the circular pivot portion from the notch in the gun barrel. The muzzle section may then be slipped from the barrel.

In order to facilitate the removal of the end portion 18 of the lever spring extension 17 from .the slot in locking ring flange 13, it is preferable to bevel one side of said slot, as at 21, so that, by forcibly turning said ring, the end portion 18 of the spring extension will ride up onto the outer face of said ring flange 13. The tension of the spring extension 17 is suflicient, however, to hold the ring against accidental movement.

I11 Fig. 7 the locking ring 14? is provided with an internal groove which is adapted to co'ope ate with a small rib 22 on the end of the locking lever. In this case, it is unnecessary to provide a retaining ring or other device as the rib on the lever will be suflicient to hold the ring against endwise movement when the parts are in locked position.

Obviously, my device admits of considerable modification without departing from my invention. Therefore, I do not wish to be limited to the specific construction and arrangement shown and described.

What I claim as my invention and desire to secure by Letters Patent is:

1. A single-barreled shotgun having an attaching portion on its forward end, a removable muzzle section having an end portion adapted to fit squarely against the end of the gun and a sleeve portion adapted to fit around the end of said gun, a locking lever 011 said muzzle section having a counterpart portion adapted to interlock with the attaching portion on the forward end of said gun, a ring revolubly mounted on said muzzle section, said ring having an annular portion adapted to lock said lever in position, and means for releasably holding said revoluble ring in looking position.

2. A single-barreled gun having an attaching portion on its forward end, a removable muzzle section having an end portion adapted to fit squarely against the end of the gun and a sleeve portion adapted to fit around the end of said gun, a locking lever on said muzzle section having a counterpart portion adapted to interlock with the attaching portion on the forward end of said gun, a ring revolubly mounted on said muzzle section, said ring having an annular portion arranged to overlap the end of said locking lever and also havin a slot in its annular portion to permit the end of the lever to pass therethrough, and a spring extension on said lever arranged to engage the slotted portion of said revoluble ring to releasably hold said parts in locked position. V 3. A single-barreled gun having a projection on the top face of its forward end and a notch in its bottom face, a removable muzzle section having an end portion adapted to fit squarely against the end of the gun and a sleeve portion adapted to fit around the end of said gun, said sleeve portion having a slot in its 1113361 edge portion adapted to receive the pro ection on the top face of the gun, a locking lever on the bottom side of said muzzle section having a counterpart portion adapted to fit in the notch in the bottom face of the gun, a ring revolubly mounted on said muzzle section, said ring having an annular portion arranged to overlap the end of said locking lever and also having a slot in its annular portion to permit the end of the lever to pass therethrough, and a spring extension on said lever arranged to engage the slotted portion of said revoluble rin to re leasably hold said parts in locked position.

cl. A single-barreled gun having a projection on the top face of its forward end and a notch in its bottom face, a removable muzzle section having an end portion adapted to fit squarely against the end of the gun and a sleeve portion adapted to fit around the end of said gun, said sleeve portion having a slot in its upper edge portion adapted to receive the projection on the top face of the gun, a locking lever on the bottom side of said muzzle section having a counterpart portion adapted to fit in the notch in the bottom face of the gun, a ring revolubly mounted on said muzzle section, said ring having an annular portion arranged to overlap the end of said locking lever and also having a slot in its annular portion to permit the end of the lever to pass thcrethrough, and a curved lateral spring extension on said lever, said extension having a forwardly nrojecting end portion adapted to fit in the slot in said revoluble ring to releasably hold said parts in locked position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses this 13th day of March, 1900, at St. Louis, Missouri.
